NASA’s Dawn spacecraft – Impact Craters on Asteroid Vesta

This image, taken December 6, 2011, combines two separate views of the giant asteroid Vesta obtained by NASA’s Dawn spacecraft. The images were taken by Dawn’s framing camera. The far-left image uses near-infrared filters where red is used to represent 750 nanometers, green represents 920 nanometers and blue represents 980 nanometers. The image on the right is an image with colors assigned by scientists, representing different rock or mineral types on Vesta, revealing a world of many varied, well-separated layers and ingredients.

The fresh impact craters in this view are located in the south polar region, which has been partly covered by landslides from the adjacent crater. This would suggest that a layer of loose material covers the Vesta surface.

Lighting Effects: Upon wakeup, a 53S subject provided a daily sleep log entry to track his sleep patterns and wakefulness. The Lighting Effects experiment hopes to better quantify and qualify how lighting can effect habitability of spacecraft. The light bulbs on the ISS are being replaced with a new system designed for improved crew health … Continue reading […]

69 Progress (69P) Launch: 69P launched from the Baikonur, Kazakhstan this morning at 2:13am CST and achieved nominal insertion with all antennas and solar arrays deployed. Due to orbital phasing, this will be a 34-orbit rendezvous profile. 69P docking is scheduled for Thursday morning at 4:43am CST. Lighting Effects: Upon wakeup, a 53S subject began … Co […]

69 Progress (69P) Launch Abort: Over the weekend, the planned launch of 69P did not occur. The vehicle issued an abort command shortly before launch and successfully shut down the launch sequence. The root cause is under investigation, and the forward plan is in work. The next available launch opportunity is tomorrow morning, Tuesday, February … Continue […]

Rodent Research 6 (RR-6): Today the crew performed the fourth day of RR-6 operations where they conducted fixative swaps and processed a series of blood samples from the rodents. The samples from today’s activities were placed in the Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI) for containment. The Rodent Research-6 (RR-6) mission uses … C […]
